Title: Hydroxylamine Hydrochloride
Post by: twodogs on October 17, 2002, 03:16:00 AM

200 gms nitromethane, 300 gms 28% HCl and 300 gms Glacial Acetic Acid were mixed and slowly heated to just below reflux and temp held there for about 4 hours then temp adjusted for relux and left for 12 hours. Left to cool for 8 hours. Crystals formed. Liquid was decanted and reduced to about 200 mls and put in freezer overnight. More crystals were recovered. Total yield 100 gms. Crystals became yellowish on standing.

Nitromethane has a nitrogen in the fifth oxidation state while hydroxylamine in the third. How is the nitromethane being reduced by GAA. I doubt the acetic acid could be so readily oxidised.
